If you thought wireless charging in smartphones was a new thing, you are mistaken as researchers have found a new method to power devices without connecting them to cords.<\/p>\n
The new method developed by Disney Research, published in the journal PLOS ONE, for wirelessly transmitting power throughout a room enables users to charge electronic devices as seamlessly as they now connect to WiFi hotspots.<\/p>\n
The researchers demonstrated their method, called quasistatic cavity resonance (QSCR), inside a specially built 16-by-16-foot room at their lab.<\/p>\n
They safely generated near-field standing magnetic waves that filled the interior of the room, making it possible to power several cellphones, fans and lights simultaneously.<\/p>\n
\u201cThis new innovative method will make it possible for electrical power to become as ubiquitous as WiFi,\u201d said Alanson Sample, associate lab director and principal research scientist at Disney Research.<\/p>\n
\u201cThis in turn could enable new applications for robots and other small mobile devices by eliminating the need to replace batteries and wires for charging,\u201d added Sample.<\/p>\n
According to Sample, wireless power transmission is a long-standing technological dream.<\/p>\n
\u201cIn this work, we\u2019ve demonstrated room-scale wireless power, but there\u2019s no reason we couldn\u2019t scale this down to the size of a toy chest or up to the size of a warehouse,\u201d Sample noted.<\/p>\n
The QSCR method involves inducing electrical currents in the metalised walls, floor and ceiling of a room, which in turn generate uniform magnetic fields that permeate the room\u2019s interior.<\/p>\n
This enables power to be transmitted efficiently to receiving coils that operate at the same resonant frequency as the magnetic fields.<\/p>\n
The induced currents in the structure are channelled through discrete capacitors, which isolate potentially harmful electrical fields.<\/p>\n
\u201cOur simulations show we can transmit 1.9 kilowatts of power while meeting federal safety guidelines,\u201d Chabalko said, adding that this was equivalent to simultaneously charging 320 smart phones.<\/p>\n
